SANDING MACHINE.

Application filed October 11, 1927. Serial No. 225,576.

This invention relates to a machine to automatically spread sand or other surfacing materials upon roadways.

The primary object of the invention is to provide a spreader which is particularly useful for spreading sand or the like on slippery, wet or icy pavements.

Another object of the invention is to provide a tiltable receptacle mounted on a vehicle with a discharging roller contacting with the tires of the machine when in tilted position to thereby rotate the roller by frictional engagement with the tires.

More specifically the sanding machine comprises a roll extending the full width of the body and projecting in a position overlying the tires of the machine, thereby oarrying a certain amount of sand or other material to the wheels to prevent slippage.

There are numerous other subordinate objects of the invention Which will be apparcut to those skilled in the art from a reading of the following specification in conjunction with the drawings attached hereto and forming a part hereof, inwhich- Figure 1 is a side elevation of the machine in its operative condition,

Figure 2 is a top view of the machine,

Figure 3 isa View partly in section show ing the body in its tilted position,

Figure 4 is a detail view on line 44 of Figure 1, and

Figure 5 is a detail View on line 5-5 of Figure l.

Referring now more specifically to the drawings, 1 represents a motor vehicle of conventional type provided with a tiltable body 2 hinged to the vehicle as at 3.- This bodymay be raised or lowered by the hand lever 5 positioned within convenient reach of the operator of the vehicle and having the flexible connection 6 secured at its end to the forward portion of the tiltable body as at 7.

The body is provided with a discharge opening 8 extending the full Width of the body and projecting beyond the tires 9 of the vehicle as at 10. Cooperating with this feed roller I provide a brush 11 adjustable by means of devices 12 whereby to Vary the thickness of the spread discharged.

tend the roller 10 the full width of the,

machine and in a position where it projects' over the tires as shown inFigure 5. By this arrangement a certain amount of sand or other surfacing material is supplied to the wheel to prevent slippage between the wheel and the feeding roller 10 and also between the wheel 9 and the roadway. This overcomes the use of chains which are impossible for satisfactory use as they interfere wit-h the transmission of power from the tires to the rolls.

In the use of the machine it will be apparent that a single operator may tilt the body forwardly, thus disengaging the roll from the tire when it is desired to skip over portions of a roadway requiring no anti-slipping medium. This is possible merely by an actuation of the lever 5.

It will be obvious that many changes and arrangements of parts may be made without departing from the spirit of the invention as expressed in the following claims:

What I claim is: j

1. A road surfacing machine comprising a tiltable body having a discharge opening in the rear end thereof, of a feed roller associated with said body and poistioned in proximity of said opening, said feed roller deriving its power from contact with the wheels of the spreader when the body is in its tilted operative position, said roller projecting over the wheels of the machine to thereby supply a relatively small amount of the discharged material on the wheels to prevent slippage.

2. A road spreading machine of the character described comprising a vehicle having a tiltablebody thereon adapted to receive surfacing materials, said body being provided with a discharge opening in the rear end thereof and a feed roller associated with the body and located in proximity to said discharge opening, said feed roller extending the full width of said body and being engageable with the tires of the vehicle to be rotated thereby when the body is in its tiltacter described comprising a tiltable body pivoted to a motor vehicle, said body having a discharge opening in the rear thereof, a feeding roller secured to said body and co operating with said opening to supply a film of surfacing material to the road, said feeding roller extending the full width of the body and overlying the wheels of the vehicle and being rotated by contact therewith, said feed roller being adapted to supply a small amount of the surfacing material to the tires to prevent relative slippage between the tires and the feed roller and the road.

In testimony whereof I afiix my signature.
